from the prong plate 5 and the handle 2I; and in Figure 5, I have shown how the prongs I, 2, 3, and 4 curve toward the convex side of the member when the apex 8 is brought into engagement with the undersurface I4 of the frame I5 and a hammer blow is applied to the protruding end I3. In this iigure, I have also shown the handle 2I sprung into place in the end ring formation I1: as well as the wall of the drawer 22, interposed between prong plate 5 and frame I5.

In Figure 6, I have shown a cross section of a front wall of a drawer with the handle secured by my novel prongs to a plate in face to face relation with the rear side and protrudingk through a slit in the rontwall.

Although in illustrating my invention, I have shown application thereof to a handle support it will be obvious that there are other uses, that parts may be modified without departing from the spirit of my invention.

Thus, this invention may be used to fasten strips of metal or metallic sheets to a wall of a container or other surface: A metallic track for a wall of a container may have prongs punched therefrom which are to curl when struck and effect the gripping action here described thus forming a durable and rigid support for the track member. f/

Many additional uses'lof my invention will now be obvious. Accordingly, I do not wish to be limited by this description, but only by the appended and concave side and an arcuate section trans# verse of said prong, edges terminating in a pointed apex the said prong being adapted to bend toward the convex side thereof, araised bead longitudinal on said prong, and a head substantially in line with said apex for receiving an impact.

3. A securing means comprising a iirst sheet of metal and a second sheet of metal; said rst sheet having integral prongs formed therein by striking up portions of the interior oi the sheet, said prongs' being substantially perpendicular to said sheet; said second sheet having two substantially parallel edges rolled back upon the sheet to form an openA loop along each of said two edges; said loops and said'prongs being positioned on their respective sheets in a manner that the prongs will register with the loops and will curl into the loops/when the two sheets areforced toward each other.

4. A securing prong for two metallic imembers comprising a prong integral with one of said members, said member being a substantially fiat plate, saidprong extending at right angles to said one of said members and having a convex and concave side and being of arcuate section on planes parallel to said one of said members, the said prong being adapted to bend toward the convex side thereof; an open loop extending alongr one edge of .the other of said members and adapted to receive said prong, the said loop being also adapted to receive the ends of a bent wire and to pivot such ends to'form a handle member,

5. In a container, a wall; a substantially flat metallic member mounted on one `face of said wall; integral prongs extending ,from said member through said wall; a second metallic member having an integral open loop to receive the prongs and to receive the ends of a bent wire and to pivot such ends to form a handle member.

6. A securing means comprising a first sheet of metal and a second sheet of metal; said rst sheet having integral prongs `rformed therein by striking up portions of the interior of the sheet, said prongs beingl substantially perpendicular to said sheet; said second sheet having two substantially parallel edges rolled back upon the sheet to form an open loop along each of said two edges; said loops and said prongsv being positioned on their respective sheets in a manner that the prongs will register with the loops and will curl into the loops when the two sheets are forced toward each other; the said loops being also adapted to receive the ends of a bent wire and to pivot such'ends to form a handle member.`
